3Com's acquisition by Hewlett Packard for $7.90/share after the close today came as a surprise to many, but not all. Because someone bought 3 times the open interest in November $5 calls and 15 times the open interest of the December calls. In summary: 3,961 Nov $5 calls were purchased today (964 open interest) for $0.65, as were 3,269 December $5 Calls (210 open interest) for $0.85. The profit, assuming the insider action was by one entity, is about $870,000 on the Novembers and $650,000 on the December strikes, for a not too shabby illegal daily P&L of $1.5 million. This is so blatant it is sufficiently stupid that even the SEC will presumably catch the perpetrator. Here's to hoping the trader ends up being Galleon's Raj Raj buying options from his E-Trade account while on bail. Of course, we fully expect any prosecution case against the perpetrator to fall apart at the seams courtesy of a completely inept legal team at the SEC and the Justice Department.

The chart below summarizes the trading action in COMS $5 near term calls.

And here one can see what a blazing outlier today's volume action was in December $5 calls.
